Abstract
An electrosurgical generator includes: a power supply configured to output a DC waveform; a power converter coupled to the power supply and configured to generate a radio frequency waveform based on the DC waveform; an active terminal coupled to the power converter and configured to couple to a first electrosurgical instrument and a second electrosurgical instrument; at least one sensor coupled to the power converter and configured to sense at least one property of the radio frequency waveform; and a controller coupled to the power converter. The controller is configured to: determine a first impedance associated with a first electrosurgical instrument and a second impedance associated with a second electrosurgical instrument based on the at least one property of the radio frequency waveform; and adjust at least one parameter of the radio frequency waveform based on the first impedance and the second impedance.
